WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 309,758, dated December 23, 1884.

(No model.)

To all whom, it may concern.-

Be it known that I, FRANK W. BRAINERD, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wire-Barbing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention is an improved wire-barbing machine embodying various novel features of construction, all of which are fully explained, described, and claimed in the following speci- 1 fication and shown in the accompanying drawings, in which Figure 1 is a plan of the entire machine; Fig. 2, a front elevation thereof, (looking in the direction indicated by the arrow a, Fig.

1,) the bed of the machine being cut by a vertical plane passing through the line as y, Fig. 1, and all in front of said cutting plane removed, Fig. 3, a side elevation (looking in the direction indicated by the arrow a, Fig. 1) of the main wire-supporting spindle C, the

sleeve C, surrounding said spindle, the gearing rotating said sleeve, and the barb-bending lever Q; Figs. 4, 5, 6, and 7, front elevations of the spindle and sleeve shown in Fig. 3, the 0 different figures showing successive steps in the formation of a barb; Fig. 8, an elevation of the barb formed by the machine; and Fig. 9, a side elevation of the sleeve and spindle, showing one of the steps in the formation of a barb. Figs. 1 and 2 are drawn to uniform scale. Figs. 3, 4, 5,6, 7, and 9 are on a scale double that of Figs. 1 and 2, and Fig. Sis actual working-scale.

In the views, A is the bed of the machine; B, the main shaft thereof, to which power is applied, and B a side shaft at right angles to the main shaft and connected therewith by miter-gears. Near the center of the bed are two stationary posts, F F, Figs. 1, 2, 3, rigidly fastened to the machine in a line parallel to the side shaft, B. The front post, F, is horizontally bored through the entire length of its upper cylindrical portion to receive the' sleeve C, which is journaled in it, and aspin- 5o dle, C, is rigidly attached to the rear post, F,

and extends forward through the sleeve C, within which itfits closely. Thepost F! and spindle C are longitudinally perforated for the passage and support of two main wires, '6 2", the distance between said perforations at the front end of the spindle being equal to the diameter of a barb-wire.

On the rear end of the sleeve C is mounted a small pinion, D, engaging with-'a larger pinion, D, immediately under it, the pinion D being mounted on a shaft, F, which is journaled in the posts F F. A second small pinion, D, is mounted on the shaft F immediately in rear of the pinion D, and engages with a geared segment, g, Figs. 1, 2, which is 6 5 formed integrally with a vertically-reciprocating lever, G, at its inner end. The lever G is pivoted near its center on a suitably-supported horizontal shaft, F, and is provided near its outer end with a horizontally-mounted antifriction roller which lies in contact with the lower curve of a cam, J, mounted on the side shaft, B. This cam forces the outer end of the lever downward, and a spring, S, attached to the lever between the shaft F and the segment 9, draws the segment downward. The cam and spring thus produce reciprocal vertical motion of the segment, and this imparts reciprocal rotation to the pinions D D D and the sleeve 0.

Across the bed of the machine extends a horizontal shaft, H, journaled in the upper ends of two stationary posts, f f, and lying considerably above the spindle C. The inner end of the shaft lies directly over the portion of the spindle which is in front of the postF, while the outer end lies directly over the shaft B. The inner end is provided with an integrally-formed downwardly-proj ecting arm, Q, of such length as to reach the upper margin of the space between the main wires i t. The lower end of the arm curves backward, and the rear and bottom faces of this curved end are cut by a continuous groove adapted to receive a barb-wire, as hereinafter set forth. The outer end of the shaft His provided with a rigidly-attached downwardly-extending arm or crank, e, on the end of which is a roller, 0', working in a groove in the face of a cam, J, on the side shaft, B. This cam gives the shaft 100 H a rocking motion and moves the arm Q from the position shown by the full lines to that shown by dotted lines in Fig. 8, and vice versa, holding it at rest in either position as long as may be desired.

As has already been stated, the spindle O is pierced longitudinally by two perforations for the passage of the main wires,and the distance between these perforations is equal to the diameter of abarb-wire. The perforations are placed one above the other, and between them is a horizontal diametrical slot extending back about an inch from the front face of the spindle, the thickness of the slot being equal to the diameter of a barb-wire. Above the slot nearly half the spindle is cut away for a distance equal to the length of the slot, the cutting plane being vertical and tangent to the upper main wire. (See Figs. 3, 4, 5, 6, 7, and 9;) The sleeve 0 is cut back flush with the rear end of the slot in the spindle, with the exception of a narrow sector, 7', which projects a short distance in front of the front face of the spindle O and forms a pin for wrapping the barb-wire about the main wire.

At the side of the spindle opposite the side shaft, B, is ahorizontal tueking-finger,P',lying in the plane of the slot in the spindle, and just in rear of the front end thereof. The finger l is formed integrally with a bell-crank lever, l, which is pivoted on a shaft, F under the bed of the machine. The horizontal arm of the lever extends outward from the pivot F its outer end lying under and in contact with the face ofthe cam J, already mentioned. The cam is provided with a lug, i, Fig. 2, adapted to strike and suddenly depress the outer end of the lever at each rotation of the shaft B.

The downward motion of the outer end of the lever 1? throws the finger I? through the slot in the spindle O, and the form of the lug t is such that the finger returns instantly after passing through the slot.

At the side of the bed opposite the shaft 13 is an intermittent barb-feeding device consisting of a pair of ordinary feed-rolls actuated by a pawl-and-ratchet mechanism, which is connected by a pitman, V, with the shaft B, and between the feed-rolls and the spindle G is an ordinary cutting mechanism consisting of a stationary knife, 0, movableknife O, and means for rocking the movable knife. As the barb-feeding and barb-cutting devices shown areQold, no particular description of them is necessary. They are the same shown and de scribed in the patent of D. O. Stover, of May 29, 1883, and are now well known and in commen use. No device for feeding the main wires is shown; but any means may be employed, the feed of the main wire being in the direction indicated by the arrow a in Fig. l.

The operation of the machine in making a barb is as follows: The main wires being in position in the perforations of the spindle, the barb-wire is fed across and between the main wires to the position shown in Fig. 4, the wrapping-sector j of the shell lying above and in contact with the free end of the barb-wire. The shell is then rotated six hundred and thirty degrees, or one and three-fourths revolution, in the direction indicated by the arrow in Fig. 4, to the position shdwn in Figs. 5 and 6, when the end m of the barb'wire is vertical. The shell then rotates about one hundred and eighty degrees in the reverse direction, for the purpose of taking the wrapping'sector out of the way of the remaining barb-forming parts,

its position at the end of such reverse rotation being shown in Fig. 6. The sector j being out of the way, the bending-arm Q is rocked backward from the position shown in full lines to that shown in dotted lines in Fig. 3. The groove in the bottom and rear faces of its curved lower end catches the upright end m of the barb and bends it downward and backward over the front edge of the cut-away portion of the spindle C until it reaches the horizontal position shown in Fig. 9. The end of the barb now lies in the plane of the horizontal slot, and a sudden thrust of the finger P swings the end through the slot into the position shown in Fig. 7. The tucked end is horizontal and at right angles to the main wires, and the severing of the barb-wire by the knives O O completes the barb. During the operation of tucking, the bending-arm Q remains in the position which it has reached in bending the end of the barb, the tuckingfinger passing under it as it enters the slot, and the tuokingdinger remains forward during the instant of severing the barb-wire. The front edge of the surface over which the end m is bent is slightly rounded, in order that the curve it gives the barb-wire may conform to the main wire when twisted around by the tucking-finger I r If the wrap of the barb be made on the main wires outside the barb-wire instead of inside, or, in other words, if the end of the barb, after the completion of the wrap, lies on the opposite side of the wrap from the face of the spindle, the end may be tucked forward instead of backward, and the split spindle may be exchanged for the ordinary solid spindle used in most other barbing-machines. In that case some suitable anvil must be provided for bending the end of the barb over before tucking it through. I have obtained the most satisfactory results, however, from the slotted spindle shown, as it presents an absolutely invariable space through which to tuck the end of the barb, while in tucking forward there is always more or less Variation in the positions of the main wires.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is*
